PROMPT 30120 MANUAL LATHES

Technical Description

The PROMPT 30120 is a heavy-duty manual engine lathe engineered for precision metalworking operations requiring substantial workpiece capacity and rigidity. This machine features a generous 29.92-inch swing over the bed, accommodating large-diameter components, complemented by a 19.69-inch swing over the cross slide for versatile turning operations. The extended 118.9-inch distance between centers enables machining of lengthy workpieces, making this lathe suitable for demanding production and job-shop applications. Equipped with a substantial 4.13-inch spindle bore, the lathe accepts large-diameter workholding devices and tooling, expanding operational flexibility. The spindle speed range extends to 2,000 RPM, providing adequate cutting speeds across various materials and applications. The machine incorporates traditional geared headstock design with hardened and precision-ground gearing, typical of conventional lathes in this class. Standard features typically include inch and metric threading capability without gear changes, manual feed control, and precision ground bed ways for accuracy. The robust construction emphasizes rigidity through heavy-duty cross-ribbed bed design and substantial machine mass, critical for maintaining tolerances during heavy cuts. This classification positions the PROMPT 30120 as an ideal choice for tool rooms, manufacturing facilities, and specialized metalworking shops requiring a versatile machine capable of handling large components with precision and reliability for turning, threading, boring, and facing operations.
